[0002] The middle support of the bridge gallows component is a right angle steel component, and needs to be one-time bending forming according to the design requirement. The one-time reverse bending of the angle steel into a right angle is a problem that has been difficult to solve in construction. In the past construction, the rib plate of the angle steel is usually cut and then bent and formed, or the angle steel is directly cut and then welded and formed. This bending method causes damage to the integrity of the component, and belongs to class A quality problem in the quality inspection and acceptance of the work section. To solve this problem, the project has developed a middle support one-time forming processing equipment, which realizes the one-time bending forming of the middle support.

The medium-frequency induction heating device is connected to one end of the steel rail conveying device and is used to heat the steel rail. The steel rail bending device is connected to the other end of the medium-frequency induction heating device and is used to perform a bending operation on the steel rail. The steel rail passes through the medium-frequency induction heating device and the steel rail bending device in sequence through the steel rail conveying device. Thus, the track bending equipment can quickly heat the steel rail through the medium-frequency induction heating device and can strongly bend the steel rail through the track bending device.
